Point-of-care testing (POCT) for key laboratory variables may help clinicians assess the level of acuteness and the level of care necessary in the management of deteriorating ward patients. We used a multibiomarker POCT panel including B-type natriuretic peptide (BNP), D-dimer, myoglobin (Myo), creatine kinase MB...

The management at the emergency department of patients presenting with symptoms of chest pain and/or acute dyspnea accounts for a substantial proportion of emergency care resources. In the work-up of these patients the blood measurements of cardiac troponins and brain natriuretic peptides are recommended by current...

Neonates nearly always experience their single largest day of blood loss on the day of birth due to admission laboratory testing. The term "admission laboratory testing" refers to the initial blood tests done when a baby is born and admitted to the NICU.  Total circulating blood volume in a 3.5 kg term newborn is 280...

Ensuring adequate oxygen delivery to tissues is a prime objective of acute/critical medical care. There is no routinely available method for directly monitoring tissue oxygenation; instead clinicians must depend on available indirect measures. Although not the only factor to be considered, measurement of the amount of ...

Myocardial infarction (MI) is the leading cause of death in the developed world. Biomarkers have an...

Fast, accurate blood gas testing is a critical component to managing the post isolated coronary artery bypass (ISO-CAB) patient in the hospital intensive care unit/coronary care Unit (ICU/CCU). Post ISO-CAB patients are admitted to the ICU/CCU after surgery mechanically ventilated. Evidence-based medicine supports...

With increasing age, an unspecific rise of fibrin degradation product in blood is observed. Thus, the D-dimer test to rule out thromboembolic events has a high false positive rate in elderly patients. In 2010, Douma et al introduced a formula to adjust D-dimer cut-off values for age in outpatients >50 years: Age ×...

In a regional top-management decision, our laboratory was given the mission to control and quality assure all POCT activities in a regional network of 10 hospitals with emergency units. Based on previous work, new region-wide recommendations, procurements,  IT connectivity, services, training, accreditation (ISO...

Emergency Department (ED) overcrowding is becoming an increasingly international issue.  Although the problem is not only resolved by ED change management (but rather requires a system-wide solution recognizing the complex interdependencies of consumer expectations, human resources, information systems immaturity and...
